SnapshotFile::time Display ends with RFC 9557 timezone annotation [+02:00] — surprising for human output

[arcker]

Summary

SnapshotFile::time is a jiff::Zoned, and its default Display includes the RFC 9557 timezone annotation suffix:

2026-05-01T10:45:42.7376742+02:00[+02:00]

The [+02:00] at the end is technically correct (RFC 9557) but unusual for end-user output. Most CLIs that show snapshot timestamps don't carry it.

Why it matters

Anything that displays snapshot time in a human-facing context (CLI listings, dashboards, log lines) ends up either accepting the noisy suffix or re-parsing+reformatting the Zoned value. The latter forces a jiff dependency on the consumer (see related issue: jiff leaked-dependency).

Suggestion

One of:

1. Add a helper, e.g. SnapshotFile::time_display(&self) -> String, returning a cleaner format like 2026-05-01 10:45:42 +02:00.
2. Document Display behavior with an explicit note ("includes RFC 9557 IANA tz annotation; use time.strftime(...) to drop it").
3. Leave formatting up to callers — but then ideally re-export jiff::Zoned (separate issue).

Workaround

Re-format on the consumer side. Not blocking.
